Last viewed items script

I am looking for a freelancer to build a PHP script which can keep track of the last 3 products a website visitor has looked at.

This information is to be displayed in a margin on the right of the page, with an image, brand name and short description for each.

When the website visitor looks at more than 3 products in a single visit to the site, ideally the last viewed items list will only display the last 3 products, as opposed to displaying everything they have viewed. (I hope that makes sense!)

If you require any further information, please let me know.

Ideally, the code will be easy to integrate with Dreamweaver 8, so it would be an advantage if the programmer usees this program to develop the code.
